Browser Checks
What a Browser Check Is
A Browser Check runs a real Playwright script in a headless Chromium browser, on a schedule, from LoadFocus cloud regions. Instead of sending a single HTTP request, it drives an actual browser through your site the way a user would, and reports the result of the whole flow.
This covers the parts of your product an HTTP check cannot see, full user journeys rather than single endpoints.
When to Use It
Use a Browser Check to verify complete user flows that an HTTP check cannot:
- Login: sign in with test credentials and confirm the account area loads.
- Search: enter a query and check that results appear.
- Checkout: add a product to the cart and walk through the payment steps.
- Forms: submit a form and verify the confirmation.
- Multi-page journeys: any flow that spans several pages in sequence.
Create a Browser Check
- Open the New API Check page.
- Choose the Browser type.
- Write or paste your Playwright script. It can use your stored variables and secrets, plus reusable snippets and setup/teardown scripts.
- Use the preview run to execute the script while editing, before you save.
- Optionally set a degraded threshold on the total duration in milliseconds. Slow but passing runs are reported as degraded, and alerts on the duration metric are supported.
- Pick your locations, frequency and alert channels, then save.
Artifacts and Results
Each run captures a full set of artifacts:
- Screenshots of the pages the script visited.
- Console logs from the browser.
- Network logs for every request the page made.
- A Trace you can open to replay the run step by step.
- Per-step timings, so you can see exactly which step slows a flow down.
- Video on failure can be enabled to watch what went wrong.
Quotas and Plans
Browser Checks are available on paid plans and have their own monthly browser-run quota, separate from API check runs. See the pricing page for current limits.
For the shared settings, frequency, locations, alert channels, activate/mute, see How to Create a New API Check. Browser Checks are part of the LoadFocus Synthetic Monitoring platform.
